After going to Dublin's Connolly Station at 9:30am on Monday to get the train to Belfast, Lord Adonis said he was aghast to discover there was no service until 11:20am.

Speaking on Twitter he said that the service should be called the "Infrequent snail" instead of the "Enterprise".

Antiquated diesel loco & carriages for 1120 Dublin to Belfast. The train is called ‘ENTERPRISE’ but it should be called ‘INFREQUENT SNAIL’ - train once every 2 hours, taking 2 hours for a distance of under 100 miles linking 2 greatest cities of Ireland! pic.twitter.com/kbFUCVerGq
